CATCH.

Application led March 26,1921.

T o all whom it may concern.'

Be it known that DANIEL W. BLACKWELL, a citizen of the United States, residing at San Diego, in the county ot San Diego and State of California, has invented a certain new and useful Catch, of which the followingir is a specification. ly invention relates to catches more particularly adapted for use in connection with door closuresbut adapted for use in connection with any stationary member and movable member where they come adjacent to each other, and the objects of my invention are: First, to provide a novelly constructed catch for supporting a movable object relatively to a stationary one; but which may be readily moved by sufiicient force; Second, to provide a catch ot this class which is positive in its action; Third, to provide a catch of this class, in which the movable object will be easily moved into position but more force required to move it in the opposite direction; Fourth, to provide a catch of this class whereby either one of the members may be mounted on either the movable or stationary object; Fifth, to provide a catch of this class, which is very simple, economical of construction, durable, easy to operate, action and which will not readily deteriorate or get out of order. 4

lVith these and other objects in View as will appear hereinafter, my invention consists of certain novelfeatures of construction,

f. combination and arrangement of parts and portions,

as will be vhereinafter described in detail and particularly set-forth in the appended claims, reference being had to the accompanying drawings and to the characters ofreference thereon which forma part of this application, in which:

Figure l, is a vlongitudinal sectional view of the operative assembly parts of the catch; Fig. 2, a sectional View lon the line 2-2of Fig. 1; Fig.*3, a front elevational view of the operative assembly parts of the catch; Fig. 4, is a sectional view through 4-4 of the `stationary plate; Fig. 5, is an edge view 6, a side elevational view thereof.

Similar characters of reference refer to the similar parts and portions throughout the several views of the drawings.

The casing l, casing head 2, revolubl latch member- 3, supporting pin 4, spring 5,

is flush with the Serial No. 455,729.

spring supporting member 6, 'and the plate constitute the of my catch.

The casingl 1, is a cylindrical member, open at its one end at l, and provided with a turned inner end portion 1P, adapted for the seat of the'large end of the spring 5. This casing 1 is provided in opposite sides with inwardly extended integral portions 1c, which are adapted for stops for the revoluble member 3. Secured in the front end of this cylindrical member 1, is the head member 2, which is secured therein by beading the end of this member 1, over the member 2, the member 2, being provided with an off set portion at the edge, so that the lmember 2 outer edge of the member 1, as shown best in Figs. 1 and 2 of the drawings. This member 2 is provided with a slot extending across the same.

P ivotally mounted in this casing l, upon -the pin 4:, to which itis secured is al revoluble catch member 3, it being notedthat the pin 4, is provided with journaled ends in the casing l, which is provided with inwardly extending portions so that the ends of the pin will not engage the object when the casing is inserted. The revoluble member 3, is provided with two extended lug portions 31 and 3b, which are adapted to eX- tend out through the notch 221 in the member 2, when themember B is turned in certain position. This revoluble member 3 is also provided with another lug 3C opposite to the lugs 3'1 and 3b. This lug 3 it will be noted is set over the center from between the lug 3a and 3b on the opposite side to provide more pressure on the revoluble member by turning on one side of the center more than on the other side, so that when closing the object, less pressure is required than when opening the object. Pivotally mounted in the lug 3c is the member 6, which is a one piece member and provided with an enlarged portion then reduced over which the small end of the conical shaped spring 5, is mounted, the other end 'of thismember 6, extending through the spring and is free for movement in either direction, the conical shaped spring vpermitting such movement. rIt will be noted that this conical spring 5 is a compression spring and in connection with the member 6 serves to support the revoluble member 3 against revolution 1n either directhe center, dependent tion on either'side of principal parts and portions said lug to engage the edge of the plate contiguous to said depressed portion revolving,r the member 3 about its axis. Then this member 3 is revolved to a` certain position the lug 3" of the member 3 will enter a hole 7b in the plato 7, holding the members 3 and 7 in a certain relative position to each other until released by a torce sufficient to overcome the spring 5.

It will be noted that the plate 7 may either be mounted on the stationary or movable member and that the casing 1 together With its assembled parts may be mounted in the other part but it is preferred to mount the casing l in the stationary part and the plate 7 on the movable part.

Though I have shown and described a particular construction, combination and rangement of parts and portions I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the purview of my invention the construction.` combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided a catch device in which one member is mounted in one portion and the other member on the other portion, that the plate 7 is provided with a double'notch and is adapted to receive one of the lugs 3b and turn the member 3 a partial revolution compressing the springr 5. That by movement when in such position, this spring must again be compressed to move it over the center therefore roviding a rctarding medium for the mova le member relatively to the stationary member. The members lc of the casing l' providing stops for the revoluble member on the opposite sides. That the position of lug 3 relative to the lugs 3b and 3El will determine the relative lamount of pressure required for moving the revoluble member yin opposite direction.

Having thus described my invention What I claim as new and desire to secure by Lettcrs Patent is: i

1. A device of the class described, including a plate provided with spaced apart recesses secured to one member, a casing secured to the opposite member, a revoluble member in said casing providedivith spaced apart lugs on its edge adapted to extend past the face of said casing and enter said recesses in said plate and a conical spring; means for controlling and retarding the movement of said revoluble member.

2. A device of the class described including a plate provided with spaced apart recesses secured to one member, a casing se cured to the opposite member, a revoluble member in said casing provided with spaced apart lugs on its edge adapted to extend past the Jface of said casing and enter said recesses in said plate and with another lugir on the opposite side ot' said revoluble member` a spring supporting1 member with one end pivotally mounted in said last mentioned lug and ay spring,r means for controlling the movement of said spring?r supporting member. 4

3. A catch of the class described including,

a plate provided with spaced apart recesses, a casing'. a revolublc member in said casinpr provided with spaced apart lugs adapted to enter said recesses in said i ate and provided with another lug positioned on the opposite side ot said revolub'le member' closer to one of said lugsthan to the other, a springY supporting'f member pivotally mounted in said -lastv'r'nentioned lug' and a conical shaped spring` with its apex engaging said spring supporting member whereby said spring,r supporting member has free movement in the base of said conical shaped spring.

In testimony whereof, l have hereunto set my hand at San Diego, California, this 19th day of March, 1921.

DANIEL W. BLACKWELL.
